Here is the latest information I have on the Canadian Military Aeronautical Communications System (MACS). If anyone has a recent electronic version of the Canadian Flight Supplement or the RAF Flight Information Handbook or ERSs, I would like to hear from you at the email address in the masthead.

Search and RescueRescue coordination center in Victoria, Trenton, and Halifax have the capability of communicating on any AEM(OR) SB frequency by utilizing phone patch facilitiesthrough their connected communication facilities. Victoria RCC also has a transmit and receive capability on 5717.0 kHz AM.During SAR operations, only those stations actively engaged in these operations will make use of 5717.0 kHz. Aircraft other than those participating in SAR operations will be instructed to change to another MACS frequency.
